BIRMINGHAM, Alabama - An 84-year-old Birmingham man is charged with first-degree assault in the accident that seriously injured a Birmingham police officer on the interstate over the weekend.

Tom Pole is being held in the Jefferson County Jail with bond set at $60,000, said police spokesman Lt. Sean Edwards. Authorities said Pole was driving under the influence of alcohol.

The crash happened Saturday night, about the same time off-duty Birmingham police Officer Keary Hollis was fatally shot not far away. West Precinct Officer Brandon Smith was working an accident on Interstate 20/59 at Arkadelphia Road when authorities say Pole struck the officer.

Smith, who played football at Ohio State, has been on the force three years. He remains hospitalized with a broken left leg, broken right elbow and a dislocated shoulder. Edwards said Smith required surgery on both the broken leg and the broken elbow.

Alabama court records show Pole was arrested in 1988 on a DUI charge, but was acquitted in that case.
